YDS-2 Type Portable Geotechnical Property Multi-functional Testing Instrument

YDS-2Portable multifunctional geotechnical property testing instrument

The instrument has passed the inspection by the China Testing Technology Research Institute, with all its mechanical performance indicators meeting the requirements.

In January 2006, organized by the Sichuan Provincial Department of Science and Technology, authoritative experts in the geotechnical engineering field assessed: "This instrument is a domestic first, with performance and indicators reaching the leading level domestically."

（1)、Features

This instrument integrates the functions of six instruments into a multifunctional testing device.

1．500KNRock press(Can perform compression, tensile, and deformation tests on rocks)；

2Rock Direct Shear Tester

3Portable Shearing ToolAvailablePerform direct shear test on the original samples of irregularly shaped rocks.Samples do not require regular geometric shapes, making them suitable for rock mass surfaces and weak rocks (such as bedding planes, fault破碎zones, fissures, sliding surfaces, weak interlayers, various shales, phyllites, schists, altered rocks, strongly weathered rocks, etc.) that are difficult to produce samples with regular geometric shapes.

4Point Load Gauge

5Mini-size gravel soil direct shear tester

6Direct Soil Clipper

This instrument showcases novelty and creativity in the concept, design, and manufacturing process, particularly in the unique straight-cut test project it features.

This instrument is designed with rationality, compact structure, and fine processing, and can be fully disassembled for packing. It boasts features such as small size, light weight, and low weight-to-power ratio. It is easy to handle, quick to install on-site, simple to use, fast in testing, and convenient for maintenance.

This instrument can test the mechanical property indicators of rocks and most of the mechanical property indicators of soil, meeting the geological survey and testing requirements of general engineering projects. Therefore, it is widely applicable to field tests by engineering geological survey teams, testing teams, colleges and universities, and scientific research institutions.

（2Primarily used for on-site or indoor testing of the following items:

1Rock deformation test

2Rock Compressive Strength Test

3Rock tensile strength test

4Rock point load strength testCan fulfillMedium to small diameter domestic drilling rigsCore and irregular samples' compressive and tensile strength tests. Minimum compressive strength testable down to 5.Mpa(soft rock), capable of testing any hard rock up to its maximum limit)

5Full Rock Direct Shear Test (suitable for domestic drilling rigs with medium to small different diameter rock cores)5cm×5cmRectangular prism (cylinder).

6Rock mass bedding and direct shear test on soft rock (suitable for irregular specimens that are difficult to process into shapes), Soft Rock Test ScopeXJ-1TypePortable shearing machine larger）；

7Soil Direct Shear Test (directly tests the shear resistance of soil cores obtained from drilling, with the shear area capable of being larger than the ring knife area)

8Direct shear test of crushed soil in natural or saturated state (gravel particle size ≤)2.0cmThe sandy gravel soil.
